asm-generic updates for 5.18
There are three sets of updates for 5.18 in the asm-generic tree:
- The set_fs()/get_fs() infrastructure gets removed for good. This
was already gone from all major architectures, but now we can
finally remove it everywhere, which loses some particularly
tricky and error-prone code.
There is a small merge conflict against a parisc cleanup, the
solution is to use their new version.
- The nds32 architecture ends its tenure in the Linux kernel. The
hardware is still used and the code is in reasonable shape, but
the mainline port is not actively maintained any more, as all
remaining users are thought to run vendor kernels that would never
be updated to a future release.
There are some obvious conflicts against changes to the removed
files.
- A series from Masahiro Yamada cleans up some of the uapi header
files to pass the compile-time checks.

sound updates for 5.18
It's been a fairly calm development cycle. There are a few
last-minute ALSA core fixes, most notably for covering PCM ioctl
races, but the most of rest are device-specific changes.
Below are some highlights:
* ALSA core:
- Fixes for PCM ioctl races that may lead to UAF
- Fix for oversized allocations in PCM OSS layer
* ASoC:
- Start of moving SoF to support multiple IPC mechanisms
- Use of NHLT ACPI table to reduce the amount of quirking required for
Intel systems
- Preliminary works forthcoming Intel AVS driver for legacy Intel DSP
firmwares
- Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with
TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek
MT8181 wideband bluetooth, nVidia Tegra234, Qualcomm SC7280, Renesas
RZ/V2L, Texas Instruments TAS585M
* HD-audio:
- Driver re-binding fix for HD-audio
- Updates for Intel ADL and Tegra234, various platform quirks for
Dell, HP, Lenovo, ASUS, Samsung and Clevo machines
* USB-audio:
- Quirk updates for Scarlett2, RODE, Corsair devices

Tracing updates for 5.18:
- New user_events interface. User space can register an event with the kernel describing the format of the event. Then it will receive a byte in a page mapping that it can check against. A privileged task can then enable that event like any other event, which will change the mapped byte to true, telling the user space application to start writing the event to the tracing buffer. - Add new "ftrace_boot_snapshot" kernel command line parameter. When set, the tracing buffer will be saved in the snapshot buffer at boot up when the kernel hands things over to user space. This will keep the traces that happened at boot up available even if user space boot up has tracing as well. - Have TRACE_EVENT_ENUM() also update trace event field type descriptions. Thus if a static array defines its size with an enum, the user space trace event parsers can still know how to parse that array. - Add new TRACE_CUSTOM_EVENT() macro. This acts the same as the TRACE_EVENT() macro, but will attach to an existing tracepoint. This will make one tracepoint be able to trace different content and not be stuck at only what the original TRACE_EVENT() macro exports. - Fixes to tracing error logging. - Better saving of cmdlines to PIDs when tracing (use the wakeup events for mapping). -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYjiO3RQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qhQzAQDtek5p80p/zkMGymm14wSH6qq0NdgN Kv7fTBwEewUa0gD/UCOVLw4Oj+JtHQhCa3sCGZopmRv0BT1+4UQANqosKQY= =Au08 -----END PGP SIGNATURE----- Merge tag 'trace-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - New user_events interface.

selftests: vm: add a hugetlb test case
Since the head vmemmap page frame associated with each HugeTLB page is reused, we should hide the PG_head flag of tail struct page from the user. Add a tese case to check whether it is work properly. The test steps are as follows. 1) alloc 2MB hugeTLB 2) get each page frame 3) apply those APIs in each page frame 4) Those APIs work completely the same as before. Reading the flags of a page by /proc/kpageflags is done in stable_page_flags(), which has invoked PageHead(), PageTail(), PageCompound() and compound_head(). If those APIs work properly, the head page must have 15 and 17 bits set. And tail pages must have 16 and 17 bits set but 15 bit unset. Those flags are checked in check_page_flags().

selftests, x86: fix how check_cc.sh is being invoked
The $(CC) variable used in Makefiles could contain several arguments
such as "ccache gcc". These need to be passed as a single string to
check_cc.sh, otherwise only the first argument will be used as the
compiler command. Without quotes, the $(CC) variable is passed as
distinct arguments which causes the script to fail to build trivial
programs.
Fix this by adding quotes around $(CC) when calling check_cc.sh to pass
the whole string as a single argument to the script even if it has
several words such as "ccache gcc".

selftests: memcg: test high limit for single entry allocation
Test the enforcement of memory.high limit for large amount of memory allocation within a single kernel entry. There are valid use-cases where the application can trigger large amount of memory allocation within a single syscall e.g. mlock() or mmap(MAP_POPULATE). Make sure memory.high limit enforcement works for such use-cases.

Pull tpm updates from Jarkko Sakkinen:
"In order to split the work a bit we've aligned with David Howells more
or less that I take more hardware/firmware aligned keyring patches,
and he takes care more of the framework aligned patches.
For TPM the patches worth of highlighting are the fixes for
refcounting provided by Lino Sanfilippo and James Bottomley.
Eric B. has done a bunch obvious (but important) fixes but there's one
a bit controversial: removal of asym_tpm. It was added in 2018 when
TPM1 was already declared as insecure and world had moved on to TPM2.
I don't know how this has passed all the filters but I did not have a
chance to see the patches when they were out. I simply cannot commit
to maintaining this because it was from all angles just wrong to take
it in the first place to the mainline kernel. Nobody should use this
module really for anything.
Finally, there is a new keyring '.machine' to hold MOK keys ('Machine
Owner Keys'). In the mok side MokListTrustedRT UEFI variable can be
set, from which kernel knows that MOK keys are kernel trusted keys and
they are populated to the machine keyring. This keyring linked to the
secondary trusted keyring, which means that can be used like any
kernel trusted keys. This keyring of course can be used to hold other
MOK'ish keys in other platforms in future"

Pablo Neira Ayuso says:
====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net coming late
in the 5.17-rc process:
1) Revert port remap to mitigate shadowing service ports, this is causing
problems in existing setups and this mitigation can be achieved with
explicit ruleset, eg.
... tcp sport < 16386 tcp dport >= 32768 masquerade random
This patches provided a built-in policy similar to the one described above.
2) Disable register tracking infrastructure in nf_tables. Florian reported
two issues:
- Existing expressions with no implemented .reduce interface
that causes data-store on register should cancel the tracking.
- Register clobbering might be possible storing data on registers that
are larger than 32-bits.
This might lead to generating incorrect ruleset bytecode. These two
issues are scheduled to be addressed in the next release cycle.

selftests: pmtu.sh: Kill nettest processes launched in subshell.
When using "run_cmd <command> &", then "$!" refers to the PID of the
subshell used to run <command>, not the command itself. Therefore
nettest_pids actually doesn't contain the list of the nettest commands
running in the background. So cleanup() can't kill them and the nettest
processes run until completion (fortunately they have a 5s timeout).
Fix this by defining a new command for running processes in the
background, for which "$!" really refers to the PID of the command run.
Also, double quote variables on the modified lines, to avoid shellcheck
warnings.

selftests: pmtu.sh: Kill tcpdump processes launched by subshell.
The cleanup() function takes care of killing processes launched by the
test functions. It relies on variables like ${tcpdump_pids} to get the
relevant PIDs. But tests are run in their own subshell, so updated
*_pids values are invisible to other shells. Therefore cleanup() never
sees any process to kill:
$ ./tools/testing/selftests/net/pmtu.sh -t pmtu_ipv4_exception
TEST: ipv4: PMTU exceptions [ OK ]
TEST: ipv4: PMTU exceptions - nexthop objects [ OK ]
$ pgrep -af tcpdump
6084 tcpdump -s 0 -i veth_A-R1 -w pmtu_ipv4_exception_veth_A-R1.pcap
6085 tcpdump -s 0 -i veth_R1-A -w pmtu_ipv4_exception_veth_R1-A.pcap

6090 tcpdump -s 0 -i veth_R2-B -w pmtu_ipv4_exception_veth_R2-B.pcap
6091 tcpdump -s 0 -i veth_B-R2 -w pmtu_ipv4_exception_veth_B-R2.pcap
6228 tcpdump -s 0 -i veth_A-R1 -w pmtu_ipv4_exception_veth_A-R1.pcap
6229 tcpdump -s 0 -i veth_R1-A -w pmtu_ipv4_exception_veth_R1-A.pcap
6230 tcpdump -s 0 -i veth_R1-B -w pmtu_ipv4_exception_veth_R1-B.pcap
6231 tcpdump -s 0 -i veth_B-R1 -w pmtu_ipv4_exception_veth_B-R1.pcap
6232 tcpdump -s 0 -i veth_A-R2 -w pmtu_ipv4_exception_veth_A-R2.pcap
6233 tcpdump -s 0 -i veth_R2-A -w pmtu_ipv4_exception_veth_R2-A.pcap

6235 tcpdump -s 0 -i veth_B-R2 -w pmtu_ipv4_exception_veth_B-R2.pcap
Fix this by running cleanup() in the context of the test subshell.
Now that each test cleans the environment after completion, there's no
need for calling cleanup() again when the next test starts. So let's
drop it from the setup() function. This is okay because cleanup() is
also called when pmtu.sh starts, so even the first test starts in a
clean environment.
Also, use tcpdump's immediate mode. Otherwise it might not have time to
process buffered packets, resulting in missing packets or even empty
pcap files for short tests.
Note: PAUSE_ON_FAIL is still evaluated before cleanup(), so one can
still inspect the test environment upon failure when using -p.

Determine an available PCR bank to be used by a test case by querying the capability TPM2_GET_CAP. The TPM2 returns TPML_PCR_SELECTIONS that contains an array of TPMS_PCR_SELECTIONs indicating available PCR banks and the bitmasks that show which PCRs are enabled in each bank. Collect the data in a dictionary. From the dictionary determine the PCR bank that has the PCRs enabled that the test needs.

If the test triggers a problem it may well result in a log message from the kernel such as a WARN() or BUG(). If these include a PID it can help with debugging to know if it was the parent or child process that triggered the issue, since the test is just creating a new thread the process name will be the same either way.

nds32: Remove the architecture
The nds32 architecture, also known as AndeStar V3, is a custom 32-bit RISC target designed by Andes Technologies. Support was added to the kernel in 2016 as the replacement RISC-V based V5 processors were already announced, and maintained by (current or former) Andes employees. As explained by Alan Kao, new customers are now all using RISC-V, and all known nds32 users are already on longterm stable kernels provided by Andes, with no development work going into mainline support any more. While the port is still in a reasonably good shape, it only gets worse over time without active maintainers, so it seems best to remove it before it becomes unusable. As always, if it turns out that there are mainline users after all, and they volunteer to maintain the port in the future, the removal can be reverted.

kselftest/vm: fix tests build with old libc
The error message when I build vm tests on debian10 (GLIBC 2.28):
userfaultfd.c: In function `userfaultfd_pagemap_test':
userfaultfd.c:1393:37: error: `MADV_PAGEOUT' undeclared (first use
in this function); did you mean `MADV_RANDOM'?
if (madvise(area_dst, test_pgsize, MADV_PAGEOUT))
^~~~~~~~~~~~
MADV_RANDOM
This patch includes these newer definitions from UAPI linux/mman.h, is
useful to fix tests build on systems without these definitions in glibc

selftests/vm: cleanup hugetlb file after mremap test
The hugepage-mremap test will create a file in a hugetlb filesystem. In a default 'run_vmtests' run, the file will contain all the hugetlb pages. After the test, the file remains and there are no free hugetlb pages for subsequent tests. This causes those hugetlb tests to fail. Change hugepage-mremap to take the name of the hugetlb file as an argument. Unlink the file within the test, and just to be sure remove the file in the run_vmtests script.

selftests: Fix build when $(O) points to a relative path
Build of bpf and tc-testing selftests fails when the relative path of
the build directory is specified.
make -C tools/testing/selftests O=build0

../../../scripts/Makefile.include:4: *** O=build0 does not exist. Stop.
Makefiles of bpf and tc-testing include scripts/Makefile.include file.
This file has sanity checking inside it which checks the output path.
The output path is not relative to the bpf or tc-testing. The sanity
check fails. Expand the output path to get rid of this error. The fix is
the same as mentioned in commit

selftests: mlxsw: resource_scale: Fix return value
The test runs several test cases and is supposed to return an error in
case at least one of them failed.
Currently, the check of the return value of each test case is in the
wrong place, which can result in the wrong return value. For example:
# TESTS='tc_police' ./resource_scale.sh
TEST: 'tc_police' [default] 968 [FAIL]
tc police offload count failed
Error: mlxsw_spectrum: Failed to allocate policer index.
We have an error talking to the kernel
Command failed /tmp/tmp.i7Oc5HwmXY:969
TEST: 'tc_police' [default] overflow 969 [ OK ]
...
TEST: 'tc_police' [ipv4_max] overflow 969 [ OK ]
$ echo $?
0
Fix this by moving the check to be done after each test case.

selftests: mlxsw: tc_police_scale: Make test more robust
The test adds tc filters and checks how many of them were offloaded by
grepping for 'in_hw'.
iproute2 commit f4cd4f127047 ("tc: add skip_hw and skip_sw to control
action offload") added offload indication to tc actions, producing the
following output:
$ tc filter show dev swp2 ingress
...
filter protocol ipv6 pref 1000 flower chain 0 handle 0x7c0
eth_type ipv6
dst_ip 2001:db8:1::7bf
skip_sw
in_hw in_hw_count 1
action order 1: police 0x7c0 rate 10Mbit burst 100Kb mtu 2Kb action drop overhead 0b
ref 1 bind 1
not_in_hw
used_hw_stats immediate
The current grep expression matches on both 'in_hw' and 'not_in_hw',
resulting in incorrect results.
Fix that by using JSON output instead.

The bigger part of the change is a revert for x86 hosts. Here the
second patch was supposed to fix the first, but in reality it was
just as broken, so both have to go.
x86 host:
* Revert incorrect assumption that cr3 changes come with preempt notifier
callbacks (they don't when static branches are changed, for example)
ARM host:
* Correctly synchronise PMR and co on PSCI CPU_SUSPEND
* Skip tests that depend on GICv3 when the HW isn't available

selftests/memfd: clean up mapping in mfd_fail_write
Running the memfd script ./run_hugetlbfs_test.sh will often end in error
as follows:
memfd-hugetlb: CREATE
memfd-hugetlb: BASIC
memfd-hugetlb: SEAL-WRITE
memfd-hugetlb: SEAL-FUTURE-WRITE
memfd-hugetlb: SEAL-SHRINK
fallocate(ALLOC) failed: No space left on device
./run_hugetlbfs_test.sh: line 60: 166855 Aborted (core dumped) ./memfd_test hugetlbfs
opening: ./mnt/memfd
fuse: DONE
If no hugetlb pages have been preallocated, run_hugetlbfs_test.sh will
allocate 'just enough' pages to run the test. In the SEAL-FUTURE-WRITE
test the mfd_fail_write routine maps the file, but does not unmap. As a
result, two hugetlb pages remain reserved for the mapping. When the
fallocate call in the SEAL-SHRINK test attempts allocate all hugetlb
pages, it is short by the two reserved pages.
Fix by making sure to unmap in mfd_fail_write.

Fix this by finding a free address using mmap instead of hardcoding
BASE_ADDRESS.

selftests/rtc: continuously read RTC in a loop for 30s
Some problems with reading the RTC time may happen rarely, for example
while the RTC is updating. So read the RTC many times to catch these
problems. For example, a previous attempt for my

kselftest/arm64: signal: Allow tests to be incompatible with features
Some features may invalidate some tests, for example by supporting an operation which would trap otherwise. Allow tests to list features that they are incompatible with so we can cover the case where a signal will be generated without disruption on systems where that won't happen.
